FIELD

The invention relates to crystalline 5-(dimethylamino)-N-(4-(morpholinomethyl)phenyl)naphthalene-1-sulfonamide dihydrochloride dihydrate, methods of preparing the crystalline salt, pharmaceutical compositions containing the crystalline salt, and methods of treatment using the crystalline salt.

BACKGROUND

Mitogen-activated protein kinases (MAPKs) are serine/threonine protein kinases that process and regulate cellular properties in response to a wide range of extracellular stimuli. These enzymes phosphorylate the OH group of serine or threonine in proteins and play important roles in the regulation of cell proliferation, differentiation, survival, and apoptosis. In mammalian cells, several distinct MAPKs have been identified, including p38 MAPK.

p38 MAPK is a class of MAPKs responsive to stress stimuli such as inflammatory cytokines and reactive oxygen species (ROS) and is involved in a wide range of signaling pathways that stimulate different biological functions. For example, p38 MAPK plays an essential role in the regulation of pro-inflammatory signaling networks and in the biosynthesis of cytokines, including tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) in immune cells.

Studies have shown that p38 MAPK contributes to the pathogenesis of chronic inflammation, which has led to the identification and development of p38 MAPK inhibitors for treating inflammatory diseases such as rheumatoid arthritis and asthma.

p38 MAPK comprises four isoforms (α, β, γ and δ). p38α MAPK was the first isoform of p38 MAPK to be identified and was first recognized as a stress-induced kinase that can be activated by lipopolysaccharide (LPS) and inflammatory cytokines. Inhibition of p38 MAPK has been shown to effectively alleviate inflammatory diseases such as rheumatoid arthritis, cardiovascular disease, and inflammatory pain.

Many p38 MAPK catalytic inhibitors are poorly effective and cause toxicity, possibly due to activity against non-inflammatory p38 and loss of p38α-dependent counterregulatory responses. p38α MAPK inhibitors that can selectively block certain p38α MAPK functions and preserve critical counterregulatory and homeostatic functions with application for the treatment of inflammatory and oncologic diseases are desired.

Accordingly, it is within the capability of those of skill in the art to assay and use compound (1) and/or pharmaceutical compositions thereof for therapy.

Compound (1) and/or pharmaceutical composition thereof can generally be used in an amount effective to achieve the intended purpose. For use to treat a disease such as cancer, an autoimmune disease or an inflammatory disease, compound (1) can be administered or applied in a therapeutically effective amount.

The amount of compound (1) that will be effective in the treatment of a particular disorder or condition disclosed herein will depend in part on the nature of the disorder or condition, and can be determined by standard clinical techniques known in the art. In addition, in vitro or in vivo assays may optionally be employed to help identify optimal dosage ranges. The amount of compound (1) can depend on, among other factors, the patient being treated, the weight of the patient, the severity of the affliction, the manner of administration and the judgment of the prescribing physician.

Compound (1) can be assayed in vitro and in vivo, for the desired therapeutic activity, prior to use in humans. For example, in vitro assays may be used to determine whether administration of a specific compound or a combination of compounds is preferred. The compounds can also be demonstrated to be effective and safe using animal model systems.

Compound (1) and pharmaceutical compositions comprising compound (1) can be used to treat a disease in which the etiology of the disease is associated with p38α MAPK protein activity.

Compound (1) dissociates in vivo to provide compound (2), which is a selective inhibitor of p38α MAPK. A selective p38α MAPK inhibitor has a higher binding affinity to the target pocket of p38α MAPK than to the catalytic binding site of p38α MAPK. A p38α MAPK inhibitor can bind to p38α MAPK near the substrate binding groove of p38α MAPK, which extends between two acidic regions, the CD and ED domains. The binding pocket can be defined at least by residues R49, H107, L108, and K165 of p38α MAPK. The binding pocket can be defined at least by residues R49, H107, L108, M109, G1 10, A1 57, V158, E1 63, L164, and K165 of p38α MAPK.

Selective binding of compound (2) p38α MAPK can be confirmed using complementary technologies. For example, a selective p38α MAPK inhibitor can show a concentration-dependent increase in melting temperature of p38α but not p38P as determined using DSF, which detects ligand-induced protein stabilization. STD-NMR, which measures low affinity protein/ligand binding via non-scalar magnetization transfer from protein to ligand protons, can be used to confirm specific compound binding to p38a and localized the interaction to its aromatic rings. A p38α MAPK inhibitor can cause a concentration-dependent increase in melting temperature of p38α MAPK. The difference in melting temperature T_(m) can be measured at a p38α MAPK inhibitor concentration of between 1 nM and 1000 μM such as at a concentration of 100 μM. For example, the difference in the melting temperature can be from 0.1° C. and about 2° C.

Compound (2) can interact with a pocket near the ED substrate docking site of p38 MAPK.

Compound (2) can bind to p38α MAPK near the substrate binding groove of p38α MAPK, which extends between the CD and ED domains.

Compound (2) can inhibit MK2 phosphorylation through interaction with p38α MAPK.

Compound (2) can competitively bind to p38α MAPK with 4-chloro-N-(4-((1,1-dioxidothiomorpholino)methyl)phenyl)benzamide.

Compound (2) can have a higher binding affinity to the p38α MAPK subunit than to the p38β MAPK subunit.

A p38α MAPK inhibitor can have a log P, for example, from −5 to 10, from −3 to 8, from 0 to 5, 0.1 to 3, from 0.1 to 1, from 0.5 to 1.5, from 0.75 to 2, from 1 to 2.5, or from 1.75 to 3. Log P is a measure of drug solubility and is defined as the logarithm of the octanol/water partition coefficient of the drug.

Phosphorylation of MK2 requires binding to the ED site adjacent to the target pocket in p38α MAPK. The target pocket can be defined by amino acids R49, H107, L108, and K165 in p38α MAPK. The target pocket can be defined by amino acids selected from R49, H107, L108, M109, G1 10, A1 57, V158, E1 63, L164, and K165 in p38α MAPK. The target pocket can be defined by the amino acids R49, H107, L108, M109, G1 10, A1 57, V158, E1 63, L164, and K165 in p38α MAPK.

Compound (2) can at least partially inhibit MK2 phosphorylation. For example, Western blotting can be used to measure inhibition of MK2 phosphorylation in anisomycin-stimulated HeLa cells by compound (2).

Compound (2) can stabilize an endothelial or epithelial barrier function. Endothelial barrier permeability can be measured by separate or combined exposure to TNFa and hyperthermia, followed by measurement of permeably for 10 kDa dextran. For example, endothelial barrier stabilization can be assessed by pretreating with compound (2), preceded and followed by permeability measurements, where stabilization can be expressed as a percent reduction in the before and after pretreatment permeability increase. A permeability increase for 10 kDa dextran can be reduced by between 5% to more than 100% such as, for example, by greater than 5%, greater than 10%, greater than 20%, greeter than 40%, greater than 60%, greater than 80%, or greater than 100%.

Compound (2) can modulate TNFa-induced gene expression in human lung microvascular endothelial cells (HMVECLs) as determined using, for example, RNASeq. For example, HMVECLs can be pretreated for a period of time with a p38α MAPK inhibitor at an appropriate concentration and then stimulated with TNFa for a period of time. Compound (1) can inhibit genes such as PRRG4, TSLP, CCLI 7, EXOC3L4, MMP9, IDOI, CXCL1O, CD200, SLCI5A3, VDR, ILIB, GPR88, CD207, TCHH, HAS3, GBPIPI, MUC4, ELOVL7, CXCL11, GBP4, PLAIA, and/or CXCL5.

The effects of a p38α MAPK inhibitor on inflammatory cytokine expression can be determined by pretreating PMA-differentiated THPI cells with a p38α MAPK inhibitor, then stimulating with LPS, and harvesting RNA a period of time later for analysis by PCR-based cytokine array. A p38α MAPK inhibitor can inhibit expression of various genes, such as IL-IA, IL-8, TNFSF8, CXCL5, CCL7, CCLI7, TNFSF9, IL-IB, CXCLI, TNFSFI5, CCL5, CCL4, CCL20, CXCL2, TNF, or BMP6. A p38α MAPK inhibitor can inhibit expression of Smad3, which drives differentiation of Foxp3 T regulatory cells and suppresses interferon-γ. Inflammation reduction can be measured by comparing the fold change mRNA levels vs. unstimulated PMA-differentiated THPI cells at various concentrations of p38α MAPK inhibitor.

Compound (1) or a pharmaceutical composition thereof can be used to treat a disease in a patient.
